Bluetooth not finding any device

[David Baumann]

I can not connect to any of my bluetooth devices.
hcitool scan runs for some seconds, then shows no devices.

WORKAROUND:

sudo add-apt-repository ppa:hanipouspilot/bluetooth
sudo apt-get update
sudo apt-get install btusb-lp1506615-dkms

I built a test module for your kernel. Install it this way

wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/bluetooth/+files/btusb-lp1506615-dkms_0.1_all.deb
sudo dpkg -i btusb-lp1506615-dkms_0.1_all.deb

If there are build errors, please post them.

Reboot after install. If the bluetooth does not work after reboot, please post output of

dmesg | grep -i blue

[Pilot6 (hanipouspilot)]

wget <url> is a one command.

[David Baumann (davidbaumann)]

You're awesome.
Now the bluetooth-led is turned on, and I can find my speaker.
But it won't connect. I used bluetooth-wizard to add the device (put it in paring-mode before).

But it's not connecting.

[Pilot6 (hanipouspilot)]

First try to pair something else, like a phone. And also please post output of

dmesg | grep -i blue

[Pilot6 (hanipouspilot)]

And also try to power off the computer, then power on. Not just reboot.

[Pilot6 (hanipouspilot)]

And also please posy output of

usb-devices | awk '/0cf3/' RS=

This output is needed to send a patch upstream.

[Jeremy (wa113y3s)]

Your speaker might need the use of

sudo pactl load-module module-bluetooth-discover

then pair with the device. If you have Blueman installed, you may have to use that command every boot

[David Baumann (davidbaumann)]

Great! Just listening to music, thank you very much!
So is there anything I can help you, developing the patch?

[David Baumann (davidbaumann)]

Should the bluetooth led really be blinking? I think it's blinking at 1hz.
Also there is some lag in music playback, running nothing but chromium, playing from local ssd.

[Pilot6 (hanipouspilot)]

I do not know about blinking, it depends on hardware.

Regarding the lags, etc it can be fixed by

sudo tee /etc/modprobe.d/ath9k.conf <<< "options ath9k btcoex_enable=1"

[Pilot6 (hanipouspilot)]

That will be applied after reboot.

[David Baumann (davidbaumann)]

So still about the LED:
It's now always on. I even did a rfkill block, but it's always on. Also if I disable using Ubuntu's bluetooth settings...

[Pilot6 (hanipouspilot)]

This should be another report about the led. It is not related to the bluetooth driver.
It can be fixed in a platform module.

[David Baumann (davidbaumann)]

Hello Pilot,

how to create a bug report about it?

Thanks for your help!

[Pilot6 (hanipouspilot)]

The same way as you created this bug report

ubuntu-bug linux

You can post a link to this bug there too.

[David Baumann (davidbaumann)]

I submitted here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1511131

[Pilot6 (hanipouspilot)]

The fix is committed. It should appear in the next kernel build.
